To all whom may concern:

Beitknown tlia.t-,WrLL ldno emit, a citizen of. the United St- :es, andn resident ofiitochester, in the county of Monroe and State of New York,have inven ted a new and In] prove l Tire-Tool, of which the 01 lowingis specitica-tion. i i

This invention relates to means for placing 1, clencher e on the rim ofan automobile wheel and elso'for re moving the some there'lrorn, duringeach of which operathe inner tube is of course not inflated.

oi my invention isto provideuueiiicient pemble device, tor the purposedescribed, cans for forcing the the out oi engagement n the inwardlyturned flange on the rim of the wheel. pted to coopera-teucith thedevice for coznpi -y removing one side of the" tire from the rim. I hovefound it desirable to provide a construction whereby the frictionbetween such device and the parts engaged thereby is reduced to thatresulting horn a. rolling contact, and I have also found it desirable toprovide means whereby cooperating rollers may be simultaneously rotat d.i I

My invention comprises then a roller and o. supportrnent thereior bymeans of which the szune may d to form n. rolling incline extendingwithin and without the tire engaging edge oi the flange on the rim tosnppo ind force the tire over the rim.

" he sjccornpsnying drawings illustrating my invention are as iollows'.

end oi the tire engaging roller. In the bearing plates I and i are boredholes to constitute bearings for the two rollers having plain portions,preferably contacting with thegploin roller a and also toothed portionsadapted to mesh with the teeth on the roller :2. The lower end 01" therod- A is tubular to receive the body of the double spring key engagingthro gh slots therefor 'in the Walls of such tubular portion alsothrough'suitably nlined holes therefor in the tubular crank bar 3 and inthe tubill? portion of the red A. The ends of the key S extend outwardlythrough the slots in the tube .8 such a distance and they are socoulorincd tint they may be forced inwardly far enough by sliding thehandle B on the tube B to permit the tube .8 to then be drawn lo11gi-,tudiimlly upon the rod A, thus forcing the extreme ou tor ends s of thekey S entirely within the inner periphery of the tube B, which, whenmoved longitudinally on the rod A tothe position indicated in Fig. 2,may be freely revolved thereon. A threaded sleeve C is seen bothSllLlLI-lll) and rotatably mounted on the rod A and threaded through.the traveling nut 0 upon opposite ends oi which are pivoted hooks 0,having free ends adapted to engage over the rim R and under the tire Tof the wheel W, as indicated in Fig. 2. The lower end of the sleeve (1has a. notch 0 adopted to be engugedby a corresponding projection a onthe upper end of the tube 13, having the crank b carrying the handle I)on its iower end.

The device may be inserted in either one of two ways, as desired, whichI will nowdescribe. The parts may be moved to the positions indicatedin'full lines in Fig. 2 with the hooks c engaging the edge of the rim Rof the wheel, then upon turning the crank b by means of the handle 1:,the parts I; a, e, {and j are forced to the positions indicated indotted lines in Fig. 2st I a, a i and j forcing the tire T inwardly alsoto the position indicstcd in dotted line at T, immediately after whichby swinging the outer or lower end of the device around, the parts maybe caused to assume the positions indicated in Figs. 1, and 7 with theroller a engaging under the edge of the tire l and the rollers eengaging the rim R, belore which the hooks 0 will of course have beendisengaged from the riinR and the sleeve 0 moved longitudinally upon therod A to the position indicated in Figs 1, 5 and 7, permitting then thered A to be seated in the 100 bearing therefor in the upper end of thestzindard O with the retaining plate 0 inserted and held in place by thepin 0; or the nut C maybe adjusted on the sleeve 0 in the first place soas to securethe relative positions ol' the parts of the device indicatedin dotted 105 lines at I, a, e, 'i and j and then the device is swungaround to the right upon its pivotal connection with the books 0 andsuch hooks 0 also swung around to the right towards the center of thewheel. Then upon drawing the device to the left to the positionpractically I the wheel may be raised.

such indicated in Fig. 2 and approximately parallel with the axis eithcwheel, the parts will becaused to assume the position already just abovedescribed with reference to the first method of inserting the device butwith the tire 'l forced to the position indicated at T alter which thedevice may be seated inits hearings in the manner already just abovedescribed. The conformation 01' the hooks c where they engage the rimltsuch as to admit ol their being swung around when in engagement withthe l'llll It as just above described.

Figs. 1, 5 and 7 show the arrangement of the device for removing thetire T lrom the rim It oi the wheel W, which operati'iui may be effectedby rotating the wheel while the device is lirinly held imposition in thestandard O, or prefer-al'ily, by turning the crank Z) by the hondlc b"lhe'standard O is pivotally supported on a plate? in such away that itmay be swung to the position indicated in Figs. 5 and 7 for removing thetire, or to the position indicated in Figs. 6 and 8 for replacing: thetire. The rear end of the loot of the standard 0 is pivotally connectedto the plate P by means of a bolt or rivet, seen only in Figs. 5 and (iand the trout edge of the foot of such standard is arranged to swingunder an inwardly extending llange 1) formed on or carried by the plateP and adapted to engage the foot of. such standard 0 when the same ismoved to either extreme position, in either oi which positions suchstandard may be held by means of a suitable pin, as shown, extendingthniiugh such flange p and into the foot of the standard 0. The plate Pis pivotally connected by means of a bolt and thumb nut as shown to theplate P adapted to extend under the axle of the wheel and receive ajaclzQl, of any preferred construction, by means of which the axle ofwhen it is desired to place the tire on the rim, the tire is forced overthe rim *rt way around the wheel and the device is inserted over the rimof the wheel and under the inner edge of the tire and then. swung to theposition indicated in Figs. 6 and S and then by either rotating thewheel or turning the crank b,-.t-he tire is carried around and over theedge of the rim R, and permitted to spring into place; The usualretaining lugs may then be screwed up and the innor tire inflated.

In most cases the device may be heldin proper posi-- tioneither forremoving or replacing the tire by means of the handle B on the tube 13without the use of the standard 0, but when the device cannot thus beheld by hand the standard 0 and its connections is made use of.

The operation of my device is believed to be sufficiently clear from theabove description to call for no further explanation. I

It is of course in'nnatoriai which edge ofthe-rim of the wheel thehooks'c, carried by the nut C, are arranged to engage, although I preferthat such hooks be adapted to engage the side of the rim towards theoperator as shown in the drawings. It will of course be understood. thatthe rod A and the tube B with the handle E ther-eon comprise means forsupporting the rollers a and a at an operative angle with the planoofthe wheel, from which the tire is to be removed, and that, as anadditional aid, the standard 0 and its connections is sometimesnecessary or desirable. By the term operative angle I mean such an angleas will secure the operation above mentioned, that is,:the angle must besuch that vthe other tire will slide ofr' from the device practicallywithin the plane of the inner edge of the flange on the rim R forplacing the tire, and lor removing it, such that the the will, insliding oil from the roller u, just pass by the outer edge of the rim R,and l'havc found with the parts proportioned as indicated in thedrawings, that, at an angle of approximately 15 degrees from the planeof the wheel, the device works very satisfactorily. The device may beused with the positions or the rollers o and a reversed, although Iprelerto use them as shown in the drawings.
